I use a large bulletin board with cork, then I covered it with some batting and then pull the batting to the back side and sew with needle and lots of long thread to sew it to hold all together on the backside pulling all edges together. I also added a small amount of padding underneath the top batting for extra cushioning. My quilting squares or blocks stick to it, plus the cork board makes it easy to use pins if I want to. To me it is easier to buy cheep batting from Walmart or elsewhere to use......
